Look at the bottom of the carburetor flange, it should have a faint stamping on it.
Did the pump work?
Did the carburetor run ok?
Why are you messing with it?
After all these years, I would bet that carb has been rebuilt at least once if not more, so getting the wrong kit in the correct carburetor would not surprise anyone who has been around old equipment. The stamp on the bottom flange will tell you what it is.
